Abstract
A polyolefin comprising a higher molecular weight component (HMW) and a lower molecular weight component (LMW), the LMW component forming 20 to 80% wt. of the polyolefin and the HMW component forming 15 to 75% wt. of the polyolefin and having a Mw/Mn of less than 10, said polyolefin having a melt strength greater than Ä0.024 x (20,000 + eta 0.05)< &circ& 0.5>Ü - 2.6 (where eta 0.05 is the melt viscosity (Ns/m<2>) at a shear rate of 0.05s<-1>); and the ratio of peak molecular weight of the high MW component over that of the low MW component is above 2.
